Hard carbon is commonly used as negative electrode in sodium‐ion‐batteries (SIBs). Another type of disordered carbon, soft carbon (SC, also known as graphitizable carbon), is considered as unsuitable for SIB applications, due to sodium storage at higher potentials and with lower capacities. However,…
Interfaces formed between porous carbon materials and ionic liquids (ILs) play an essential role in catalysis as well as in electrochemical energy storage and energy conversion. Profound knowledge about the formed local structures on a molecular level is essential to create the desired physicochemical…
Polycrystalline, hexagonal HoMnO3 thin films sandwiched between an un-patterned Pt/Ti bottom electrode and a circularly patterned Al top electrode reveal forming-free, polarity dependent predictable and random, unipolar resistive switching with stable retention, and a resistance ratio between high resistance…
Embedding quantum dots into porous matrices is a very beneficial approach for generating hybrid nanostructures with unique properties. In this contribution we explore strategies to dope nanoporous SiO 2 thin films made by atomic layer deposition and selective wet chemical etching with precise control…
Using magnetic nanoparticles (MNPs) for extracorporeal heating applications results in higher field strength and, therefore, particles of higher coercivity can be used, compared to intracorporeal applications. In this study, we report the synthesis and characterization of barium hexa-ferrite (BaFe₁₂O₁₉)…
Memristors, since their inception, have demonstrated remarkable characteristics, notably the exceptional reconfigurability of their memory. This study delves into electroforming-free YMnO 3 (YMO)-based resistive switches, emphasizing the reconfigurable memory effect in multiferroic YMO thin films with…
Understanding the relationships between structure and properties of aluminosilicate glasses is of interest in magmatic studies as well as for glass applications as mechanical or optical components. Glass properties may be tailored by the incorporation of additional elements, and here we studied the effect…

Abstract Understanding the multivariate origin of physical properties is particularly complex for polyionic glasses. As a concept, the term genome has been used to describe the entirety of structure‐property relations in solid materials, based on functional genes acting as descriptors for a particular…
Using magnetic nanoparticles for extracorporeal magnetic heating applications in bio-medical technology allows higher external field amplitudes and thereby the utilization of particles with higher coercivities (H C ). In this study, we report the synthesis and characterization of high coercivity cobalt…
Sample degradation, in particular of biomolecules, frequently occurs in surface‐enhanced Raman spectroscopy (SERS) utilizing supported silver SERS substrates. Currently, thermal and/or photocatalytic effects are considered to cause sample degradation. This paper establishes the efficient inhibition of…
Abstract Porous platinum is a frequently used catalyst material in electrosynthesis and a robust broadband absorber in thermoelectrics. Pore size distribution and localization determine its properties by a large extent. However, the pore formation mechanism during the growth of the material remains unclear.…
Abstract We report on surface elasticity, plastic deformation and crack initiation of chemically strengthened soda‐lime silicate and sodium aluminosilicate glasses during lateral indentation and scratch testing. Instrumented indentation using a normal indenter set‐up corroborated previous findings on…
Abstract A conductive polymer (poly( p -phenylenevinylene), PPV ) was covalently modified with Ru II complexes to develop an all-polymer photocathode as a conceptual alternative to dye-sensitized NiO, which is the current state-of-the-art photocathode in solar fuels research. Photocathodes require efficient…

We have developed an efficient, low temperature, synthetic route for ZnO nanoflowers (NFs) as photoanode material. This alternative route yields small flowerlike nanostructures, built from densely self-assembled tip-ended rod structures. The obtained ZnO NFs possess a large bandgap of 3.27 - 3.39 eV,…
